In the drawing which illustrates a pre- Fig. 2 is an elevational view of the installation shown in Figurel' as it appears when viewed from the right of the figure Fig. 3 is'a view showing the manner-of assembling the stud-part of the installation; and-" Figs."4, 5 and 6 show a bottom, a side and'a plan view respectively of the stud as it api pears before attachment to a support. 1 Referring to the particularembodiment of our inventionselected for illustration by the drawing we have shown a snap fastener stud particularly,thoughnot exclusively, adapted for upholstery work.

In automobile body manufacture it has been I found advisable to-secure some of the up- 7 holstery work in place by means of snap fa'steners. The upholstery is made up in panels and is therefore very easily attached to and detached from the frame work. It is some times desirable to make up the upholstery of backing and covering material and assemble the fastener members thereto just prior to securing the upholstery to the framework and it is just such an installation and fastener adapted for that use that we have shown in the drawing. 7

A very simple installation is illustrated, comprising a frame part 1 of sheet metal having an aperture 2 therethrough, an upholstered part comprising a backing 3 of cardboard or the like, one side of which is covered by cloth 4 or other flexible material, and a snap fastener stud member securing the upholstered part to the frame 1, as shown in Figs. 1 and 2.

The stud member up from a strip of sheet metal and before attachment (Figs. 3 through 6) has a collapsible base 5, which base is herein shown as' formed by bending the strip of sheet metal herein shown is folded 66 to move toward each other and spring 1930. Serial No; 455,259.

in the middle providing portions which-diverge and then converge again (Fig. 3) to form a hollow square. The ends 6 6 of the strip may extend face to face in the direction of a diagonal of this square and conveniently may be longitudinally split for a part of their length, the material at one side of'the split being turned over to provide a flange or attach- CAMBRIDGE, MJASSAGHUSETTS, A COR-- ing part 9 in spaced relation to the base These twoattaching'parts 9 are preferably respectively on opposite sides of the center line. The remaining portions of the strips have outer edges which diverge and then converge in cooperation to provide a stud head 7 p and neck 8.

The base 5 is preferably scored by notches "10, preferably at the corners of the square so that the hollow square may be flattened, its

sides folding together about these corners (Fig. 1) for the purposes presently to be described.

When the stud member is constructedin the manner described and is to be attached. to

a pre-assembled upholstered part, it may be attachedin the manner shown in Fig. 3. In"

that figure the base is entered through apreformed aperture 11 in the backing 3 .shown as square in outline. The flexible material or covering 4 is pressed away from the backing 3 to permit passage of the base 5 of the base to a position shown in Figure 1. Thus the fastener can be easily and quickly applied 1 to the upholstery at any time either before or I after the covering material has been applied to the backing. The attachment is simple because the base engages one face of the back ingafter it has been flattened and' the attach-- ing parts 9-9 engage theoppositeface of the carrying medium. [Our improved stud and means of attachment is formed entirely from a single piece of metal and after thejbase is set it is suffi= ciently yieldable to permit the projections them back again when forcedthrough a studreceiving aperture. The stud is cut out of fiat sheet material and-by a'series of simple in spaced relation to said base and .located 1, between the base and the free end of the means extending from the base.
